Too few sampled comments (4) to say how often HN recommends it.?

Why HN links it

HN readers cite John Englander's posts as support for claims about long-term climate history, such as CO2 and temperature charts over 420,000 years and Florida's elevation. Commenters link them without judging the writing.

Summarised by Claude from a sample of 4 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?

  1. Temperature variations in ancient times are very unreliable, because they can only be inferred indirectly. The big giveaway for anthropogenic climate change is co2 concentration, since we can directly measure its value hundreds of thousands of years in the past thanks to air bubbles enclosed deep in glaciers: https://climate.nasa.gov/climate_resources/24/graphic-the-re... It clearly shows that the atmosphere never l…

  2. No, it isn't. It's 100 feet, or 30 meters. See: https://www.worldatlas.com/articles/us-states-with-the-lowes... https://vacationidea.com/florida/highest-elevation-in-florid... https://johnenglander.net/florida-is-not-going-underwater-an...

  3. Given that you haven't said when scientists predicted this I think this comment is a bit of a strawman. When atmospheric CO2 levels were at this level, 3-5 million years ago, sea levels were 30 feet higher than today. So why hasn't that happened yet? Because it takes A LOT of energy to melt that amount of ice, but just because it hasn't happened yet doesn't mean it won't or can't. It just will likely not happen in o…

  4. I don't see cooling, I see 5 yr trend being warming and 2021's 12M average not done yet. Averages are slower and can hide information, though new records will arrive next year when whole 2021 is accounted for. Earliest signal due in 6 months after July 2021. Longer term graphs should raise concern for existing life today: https://johnenglander.net/chart-of-420000-year-history-tempe... And why: https://climate.nasa.g…
